.. COMMENT use https://pythonhosted.org/sphinxcontrib-httpdomain/ to
.. document the REST API.

=================
Docker Remote API
=================


1. Brief introduction
=====================

- The Remote API is replacing rcli
- By default the Docker daemon listens on unix:///var/run/docker.sock and the client must have root access to interact with the daemon
- If a group named *docker* exists on your system, docker will apply ownership of the socket to the group
- The API tends to be REST, but for some complex commands, like attach
  or pull, the HTTP connection is hijacked to transport stdout stdin
  and stderr
- Since API version 1.2, the auth configuration is now handled client
  side, so the client has to send the authConfig as POST in
  /images/(name)/push

2. Versions
===========

The current version of the API is 1.10

Calling /images/<name>/insert is the same as calling
/v1.10/images/<name>/insert

You can still call an old version of the api using
/v1.0/images/<name>/insert


v1.10
*****

Full Documentation
------------------

:doc:`docker_remote_api_v1.10`

What's new
----------

.. http:delete:: /images/(name)

   **New!** You can now use the force parameter to force delete of an image, even if it's
   tagged in multiple repositories.

.. http:delete:: /containers/(id)

  **New!** You can now use the force paramter to force delete a container, even if
  it is currently running

v1.9
****

Full Documentation
------------------

:doc:`docker_remote_api_v1.9`

What's new
----------

.. http:post:: /build

   **New!** This endpoint now takes a serialized ConfigFile which it uses to
   resolve the proper registry auth credentials for pulling the base image.
   Clients which previously implemented the version accepting an AuthConfig
   object must be updated.

v1.8
****

Full Documentation
------------------

:doc:`docker_remote_api_v1.8`

What's new
----------

.. http:post:: /build

   **New!** This endpoint now returns build status as json stream. In case
   of a build error, it returns the exit status of the failed command.

.. http:get:: /containers/(id)/json

    **New!** This endpoint now returns the host config for the container.

.. http:post:: /images/create
.. http:post:: /images/(name)/insert
.. http:post:: /images/(name)/push

  **New!** progressDetail object was added in the JSON. It's now possible
  to get the current value and the total of the progress without having to
  parse the string.

v1.7
****

Full Documentation
------------------

:doc:`docker_remote_api_v1.7`

What's new
----------

.. http:get:: /images/json

   The format of the json returned from this uri changed.  Instead of an entry
   for each repo/tag on an image, each image is only represented once, with a
   nested attribute indicating the repo/tags that apply to that image.

   Instead of:

   .. sourcecode:: http

      HTTP/1.1 200 OK
      Content-Type: application/json

      [
        {
          "VirtualSize": 131506275,
          "Size": 131506275,

          "Tag": "latest",
          "Repository": "ubuntu"
        },
        {

          "Tag": "precise",
          "Repository": "ubuntu"
        },
        {
          "VirtualSize": 180116135,
          "Size": 24653,
          "Created": 1364102658,
          "Id": "b750fe79269d2ec9a3c593ef05b4332b1d1a02a62b4accb2c21d589ff2f5f2dc",
          "Tag": "12.10",
          "Repository": "ubuntu"
        },
        {
          "VirtualSize": 180116135,
          "Size": 24653,
          "Created": 1364102658,
          "Id": "b750fe79269d2ec9a3c593ef05b4332b1d1a02a62b4accb2c21d589ff2f5f2dc",
          "Tag": "quantal",
          "Repository": "ubuntu"
        }
      ]

   The returned json looks like this:

   .. sourcecode:: http

      HTTP/1.1 200 OK
      Content-Type: application/json
      
      [
        {
           "RepoTags": [
             "ubuntu:12.04",
             "ubuntu:precise",
             "ubuntu:latest"
           ],
           "Id": "8dbd9e392a964056420e5d58ca5cc376ef18e2de93b5cc90e868a1bbc8318c1c",
           "Created": 1365714795,
           "Size": 131506275,
           "VirtualSize": 131506275
        },
        {
           "RepoTags": [
             "ubuntu:12.10",
             "ubuntu:quantal"
           ],

           "VirtualSize": 180116135
        }
      ]

.. Warning::

  The /build improvements are not reverse-compatible. Pre 1.3 clients
  will break on /build.

List containers (/containers/json):
